Hydration status, executive function and response to orthostatism following a 118-km race: are they interrelated?

The present study aimed to explore whether blood pressure (BP) and heart rate (HR) variability (HRV) responsiveness to orthostatism, jointly with executive function (EF) performance, was diminished after an ultra-endurance mountain race. Besides, we wanted to assess whether hydration status was related to either performance or the abovementioned alterations. Fifty recreational ultra-endurance athletes participating in the Penyagolosa Trails CSP115 race (118 km and a total positive elevation of 5,439 m) were evaluated before and after the competition. The HRV and BP were measured in response to an orthostatic challenge. The EF was evaluated using the color-word interference task of the Stroop test. Body mass (BM) and urine specific gravity (USG) changes were used to assess hydration status. The HRV and BP responsiveness to orthostatism was diminished after the race. Besides, a significant BM loss of 3.51 ± 2.03% was recorded. Conversely, EF and USG showed no significant changes from prerace to postrace. Eventually, BM loss was inversely related to finishing time (r = −0.34) and postrace orthostatic HR and EF were positively associated (r = 0.60). The USG and BM loss appear to provide different insights into hydration status, and our results challenge the well-established criteria that BM losses >2% are detrimental to performance. Coaches are advised to consider athletes' performance level when interpreting their BM changes during an ultra-endurance competition. Similarly, coaches should be aware that increased vulnerability to orthostatism is a common phenomenon after ultra-endurance races, and diminished HR responsiveness to orthostatism could constitute a practical indicator of EF worsening.

Percepción del alumnado sobre el uso del método AICLE en Educación Física: estudio de caso
Salvador-Garcia, Celina; Chiva-Bartoll, Oscar; Vergaz Gallego, Juan José
El Aprendizaje Integrado de Contenidos y Lengua Extranjera (AICLE) está siendo cada vez más extendido e investigado en el panorama
educativo español. Dada la importancia de la motivación y la predisposición del alumnado para que el proceso de enseñanza-aprendizaje sea efectivo,
este estudio de caso analiza la percepción de un grupo de secundaria durante la aplicación del método AICLE en la asignatura de Educación Física. Se optó
por un enfoque metodológico cualitativo apoyado en la triangulación de diarios de reflexión del alumnado, registro anecdótico del profesor-investigador
y un focus group. Los resultados afianzan el actual estado de la cuestión, desvelando cinco categorías sobre las que se conforma la percepción del
alumnado: temor a la lengua, motivación y participación en la asignatura, aprendizajes específicos de Educación Física, mejora de la expresión oral en
inglés e importancia del inglés para el futuro académico-profesional. En conclusión, el estudio desvela cómo de la aprensión inicial hacia el AICLE,
derivado del temor a la lengua, se pasó a un incremento progresivo de la participación del alumnado, ligado a una creciente percepción de mejora de la
propia competencia comunicativa.; Content and Language Integrated Learning (CLIL) is becoming more widespread and studied in the Spanish educational panorama. Due to
the importance of motivation and predisposition of students for an effective development of the teaching-learning process, the present case study
analyses the perception of a secondary school group about their implementation of the CLIL method in Physical Education subject. A qualitative
methodological approach was adopted, supported by the triangulation of students’ reflection diaries, the teacher-researcher’s anecdotal register and a
focus group. The results reinforce the current status of the issue, uncovering five categories according to the students’ beliefs: fear for the language,
motivation and participation in the subject, specific Physical Education learnings, improvement of oral expression and magnitude of English language
for their academic-professional future. In conclusion, this research discloses how during the intervention an initial apprehension towards CLIL related
to the fear for the language, turned into a progressive increase of the students’ participation, linked to an improvement of the self-perception of
communicative competence.

Este artículo propone y justifica el juego motriz como herramienta
metodológica para niños y niñas con síndrome de Down. El juego motriz fomenta un
estilo de vida saludable basado en la actividad física y el deporte y, además,
favorece el desarrollo integral de todos los participantes. A lo largo del texto se
justifica porqué los juegos motrices son adecuados especialmente para los niños y
niñas con síndrome de Down, ofreciéndose además diversas pautas metodológicas
que resulta interesante tener en cuenta a la hora de llevarlos a cabo. Por último, se
presentan varios juegos a modo de ejemplo de la propuesta.; This paper suggests and justifies gross motor games as a methodological tool for children with Down syndrome. Gross motor games foster a healthy lifestyle based on physical activity and sport.
Besides, they enhance the comprehensive development of participants. Throughout the text gross motor games are argued to be especially fit for children with Down syndrome, offering methodological guidelines to take into consideration when carrying them out. Finally, some games
are introduced as a suggestion.

The link between resting-state functional connectivity and cognition in MS patients
Cruz Gómez, Álvaro Javier; Ventura Campos, Mercedes; Belenguer Benavides, Antonio; Avila, Cesar; Forn, Cristina
Background/Objective: The objective of this paper is to explore differences in resting-state functional connectivity
between cognitively impaired and preserved multiple sclerosis (MS) patients.
Methods: Sixty MS patients and 18 controls were assessed with the Brief Repeatable Battery of Neuropsychological
Tests (BRB-N). A global Z score of the BRB-N was obtained and allowed us to classify MS patients as cognitively
impaired and cognitively preserved (n = 30 per group). Functional connectivity was assessed by independent component
analysis of resting-state networks (RSNs) related to cognition: the default mode network, left and right frontoparietal
and salience network. Between-group differences were evaluated and a regression analysis was performed to describe
relationships among cognitive status, functional connectivity and radiological variables.
Results: Compared to cognitively preserved patients and healthy controls, cognitively impaired patients showed a lesser
degree of functional connectivity in all RSNs explored. Cognitively preserved patients presented less connectivity than
the control group in the left frontoparietal network. Global Z scores were positively and negatively correlated with brain
parenchymal fraction and lesion volume, respectively.
Conclusion: Decreased cognitive performance is accompanied by reduced resting state functional connectivity and
directly related to brain damage. These results support the use of connectivity as a powerful tool to monitor and predict
cognitive impairment in MS patients.
